u-MgF2复合纳米颗粒薄膜的光学非线性特性
Optical Nonlinear Characteristic of Cu-MgF2 Nanoparticle Films
用射频磁控溅射镀膜装置制备的Cu-MgF2复合纳米颗粒薄膜，纳米Cu颗粒的粒径为10.5～23.3nm，表面等离子激元共振吸收峰随Cu颗粒体积分数和颗粒粒径的增大而朝长波方向移动。当Cu体积分数 时，在 附近，最大吸收系数 cm-1，三阶光学非线性折射率系数 cm2/W，非线性折射率 esu，三阶光学非线性响应 esu，优值比 。
Investigation was made on the nonlinear optical characteristic of Cu-MgF2 nanoparticle films with different Cu fraction and varying Cu particle diameter from 10.5 to 23.3 nm. The results show that the surface plasmon resonance peak for Cu nanoparticles shifts towards long-wave side as Cu fraction increases. When Cu fraction and around , maximum absorption coefficient cm-1; third-order nonlinear optical refractive coefficient cm2/W; nonlinear refractive index esu; and figure of merit .
